Can we add RLS with page level + region level together?

 ,Understand the Limitation Power BI does not support page-level security. RLS works only on data (rows), not on report pages. So page visibility cannot be controlled using RLS alone

Step 1: Create a Region-based RLS role. Filter data using:
[Region] = USERPRINCIPALNAME()
(or via a User-Region mapping table)

This ensures clients see only their region’s data across pages

Step 2: Create an Internal Users Role: Create a separate role like Internal_Full_Access. Do not apply any data filter. Assign internal users to this role. Internal users will see full data
Step 3: Hide the Internal Page: Right-click the 5th page, Select Hide page

Hidden pages: Are not visible in report tabs and Can only be accessed through navigation
Step 4: Create Navigation Buttons: Add buttons for page navigation
Create a DAX measure to identify internal users:
IsInternalUser =
IF(
   USERPRINCIPALNAME() IN {
       "[email protected]",
       "[email protected]"
   },
   1,
   0
)
Step 5: Control Button Visibility: Select the button for the 5th (internal) page
Go to Format → Action → Visibility
Bind it to the IsInternalUser measure. Button appears only for internal users
Step 6: Final Result, Clients see only 4 pages, Data filtered by Region RLS and Internal Users can see all 5 pages, Have full data access

Important Note:
Hidden pages are not real security
Sensitive data must still be protected using RLS
If strict security is required, create two separate reports using the same dataset
